Question: To protect baby scallops and ensure the survival of the

To protect baby scallops and ensure the survival of the species, the U.S. Fisheries and Wildlife Service requires that an average scallop must weigh at least 1/36 pound. The harbormaster at a Massachusetts port randomly selected 18 bags of scallops from 11,000 bags on an arriving vessel. From each bag, agents took a large scoop of scallops, separated and weighed the meat, and divided by the number of scallops in the scoop, finding a mean weight of 1/39 pound.
(a) Would the population of 11,000 bags be considered effectively infinite in this case?
(b) Which value represents a sample statistic: 1/36 or 1/39? (Data are from Interfaces 25, no. 2 [March–April 1995], p. 18.)
